Beit known that I, CHRISTIAN NUIIANN, a citizeny ofthe United States,residing at St.

Louis, inthe State of Missouri, have invented v certain new and usefulImprovements in Pressure-Blowers, of which theifollowin is a speciiication, reference being had therein to vthe accompanying drawings.

` This invention relates to improvementsl in i This invention consistsof a revolving menu ber within a casin for creating a ra'pid cur'-` rentof air to be distributed through tubing vto any point.

, The lobj ect of this invention is" to provide a revolvin member withpassalges terminating outward y from the axis, co ecting air and,ldelivering it under pressure through said passages into a chamber formedi'n the casing of the blower, from whence it is distributed.l

" Figure y1 is a verticallongitudinal sectional view takenv on the line1 l'of Fig. 2 viewing v in the direction indicated by the arrow. Fig.v 2is a vertical cross-sectional view taken ony the line 2 2 of Fig-Llviewing in the direction indicated by'the `arrow. Fig. 3 is adetail.

Anair-receiving chamberS In the construction og thedevice as shnwn I provide an criteri-'casing 4, comprisingr two verticalwalls 5 and 6, Veach havlng central openings 7, through which the air isadmitted is formed inthe casing', 4 bythe outer periphf ery 9 and 'thedivisions 10, 1;:1'; and 12. 'Passages 13 are formed between the overlaping ends of the divisions, through whichjt e air under pressure isdischar ed' into .the air-reeiving chamber 8 from t and gradua lyincreasing in size, terminating tached. i

bearing 16, held in the center of the'2 openings Aarms 17. In thesebearings is support'-V ofa disk 20,l rim 21, an outer casting 22,

Theair-receivin chamber is constructed fin the form of a he ix,beginning with a nar-l row openin as indicated by the numeral 14.-,v

l drivingshaft 18, upon whichis rigidlyVv untedthe, revolving member 19,4consist-- rim are vformed integral, and to said rim is fastened in any*suita ble manner the castings 22 and 23'. The rim 21 has'a plurality ofopenings or slots 24. Also passages 25v are formed in the outer casting22 in -alinement with the slots 24, forming an outlet -through which theair is passed from the center ofthe revolving member to the chamber 8.*I

The outer corners of the passages 25 are curved, as. indicated by thenumeral 26.

This is for the purpose ofdeflecting the air as it passes Jfrom thepassages 25 in the direc-iv -surface of. the passages, then outwardlythrough the lsaid vassages'and into thel spaces between the revo vingmember and divisions. The air in these spaces is forced out int/o thevair-receiving chamber 8"by the corners of the revolving member by ywayof the passages 13;

Qn each side of the rim 21 and extending downwardly a shortv distancebeyond the lowest edge ofthe inner castings 23 is a ring 30, which Vhasa tendency to retain the air from, passing sidewise and lodging betweenthe revolving member' and wal s ofthe cast will be observed that thespaces between lthe divisions and periphery of thecasing formingl thereceiving-chamber yincrease in size from al quarter to a half, fromahalf to three-quarters, `irom `three- .1uarters to a whole, theexpressionl quartef indicating its starting-point, and whole indicatingits outlet or discharge end.

The revolving` member is 4operated in the direction indicated by thearrow 2, the air being `admitted through'the central'ope'nings 7 in thelwalls 5 and 6. The air coming into. f The walls: 5 andj are eachprovided witha the rapidly-revolving lmemberl is agitated, saidair-.having a tendency to move toward'v IOC' The operation of myinventionv is as follows:

` the eriphery and coming in contact with the su aces 28 giving it amovement as indim cated bythe arrows 3. y The current of air thencomes-in contact `with the ends 27 ani is then deflected outwardlythrough the I it) sages 25. The outlets'of the passages 25 are smallerthan the, remaining portion, and by this construction a pressure iscreated. The air at this point being under pressure ajourrent lis formedtraveling a course as indicated by the arrows 4 and then dischargedthrough the passages 13 yinto the receivin -chamber 8, Where in thisinstance the air wi l take the course as indicated by the arrows 5 andthen out through the outlet 15. --v

' Having fully described my invention, what I claim is- A blower of theclass described comprising an outer casing7 divisions located in saidcas- 'i 5 ing, dividing said casing into two chambers,

the ends of said divisions overlapping, forming passages for the air, arevolvingmember secured to the inner and outer sides of said rim andprovided with openings through which the air may pass, substantially asspecified.

In testimony whereof I ,hereunto set my hand this 19th day of January,1905.
